IMPRovEMENTlN sTovEs FOR HEATING WATER.

Specification forming part of Letters Patent No. 129,922, dated July 30,r1872.

To all whom 'lt may concern:

Be it known that I, EDWARD BWURNE, of Pittsburg, in the countyoi`Allegheny and State of Pennsylvania, have invented a new and usefulImprovement in Stoves designed for Heating Water and for other purposes.

The nature of my invention will be readily understood by the followingdescription, taken in connectionwith the accompanyingdrawing, wherein-Figure 1 represents a perspective view of 'my improvedstove; Fig. 2, atransverse vertical section of the same.

To construct :my stove I make a large metallic tank, A, capable ofholding fifty or sixty gallons of water, and of such a shape as toembrace the iire on its sides and reach around its back. This tank Iform of a single piece of metal by casting it entire, by which it ismade cheaper, more durable, and less liable to get out of order thanwhen constructed of several pieces. -It is then adjusted upon abutmentswithin a shallow cast-iron box or bed-frame, B, of similar shape, and soarranged with rela- `tion thereto as to leave a space, C, between thebottom of the tank and the interior of its supporting-frame, and also alike space, D, completely around that portion of the tank immediately inthe rear of the fire-place, which fire-place E is fitted with a grate ofthe open ordinary kind, but closed at the top at a little distance fromthe tank. Behind the tire is introduced a thick verticalplate, P, soperforated or piercedwith numerous holes as to give free escape to theproducts of combustion through -them in that direction. A plain orornamental casing, F, of cast-iron is placed over the tank and fire-box,the upper horizontal plate H of which is arranged sufficiently highabove the top o'f the tank to afford a broad shallow space between thetwo; this is divided by a vertical wall, f, having therein an opening,g, leading directly into the chimney k, which opening is provided with aVslidimng door or damper, R, that may be operated by means of a rod, N,extending to the outside. The upper plate or tablet H of the stove hasalarge central opening therein, covered by a conical polygonal cap, T,constructed with a central divisionwall, W, the lower edge of whichmeets and rests upon the upper edge of the perforated plate P at theback of the fire, while it extends upward so nearly to the inside apexof the cone as to leave but a narrow passage, e,

at that point, through which a portion of the' heat and escapingproducts of combustion are compelled to pass on their way to thechimney, and by so passing increase the heat of the cone. This conicalcap T is constructed and applied to the stove for the purpose of andintended to facilitate the heating of sad or ilat irons, which may bearranged point upward around it, with their faces reclining against itsnumerous sides, and their bases resting withinthe encompassing-ring J,by which they are kept from sliding away; or, if circumstances requireit, the cone may be removed and supplemented by a simple flat platehaving therein one Vor more kettle-holes, such as are foundin ordinarycooking-stoves. The front of this stove, directly above the grate, isprovided with an inclined chute, L, through which all the fuel thatsupplies the fire is introduced; vand for the purpose of preventing theescape of smoke in that direction said chute is furnished with atightly-ttin g door, S, so hinged thereto as to be easily opened orclosed. The tank is also provided with an inlet-pipe, a, situate at oneend near the top, and an outlet-pipe, b, at the' same end near thebottom, by which a continuous supply and circulation of water may bekept up.

T he several parts of this stove being con structed, combined, andarranged as shown, it will be seen that on opening thedamperR thetendency of the heat to ascend, together with the smoke and otherproducts of combustion, will cause them to pass partly through theopening ein the apex of the cone and para ly through the holes in thedisvision-plate P, after which they traverse the top of the tank A ontheir way to the chimney, and thus escape into the atmosphere. Byclosing this damper the currents -of heat, smoke, &c., will, on reachingthe rearof the division-wallP, flow downward, and after circulatingunder the tank eventually pass up its back onward to the chimney, thus,to a very considerable ex tent, increasing itsheating-surface.

Claims.

I claim 1. A stove and water-heater so constructed with a perforateddivisionwall, P, at the back of the re as to form a ue, D, between itand the tank A, by which the heat and products of combustion maybe madetopass down under and around the tank on their Way to the chimney, inthe manner shown, for the purposes set forth.

2. I claim a stove and Water-heater so constructed and combined With aconical polygonal cap, T, provided with a central divisionwall, W, andopening e, as that a portion of the heat and accompanying products ofcornbustion may be made to traverse, in an up-anddown direction, theinside of' said conical cap, on their way to the chimney.
